unable to connect to network domain...pls help

[d-brain]

Hi all, i hope some of u out there r willing 2 help me out...here goes...

I've installed two computers with Red Hat 7.1, ( one is the server, the other a client ) but i could not connect these two together. I've tried configuring using NFS, linuxconf and also OPENSSH but still it didn't work.

Some errors include connection refused and name or service not known.

Please advice.
Thanks

First, do you have basic connectivity between the two computers? Can you ping back and forth between the two?

If you can, then check for a firewall. The default firewall from a Red Hat install will block most traffic. On both machines, execute as root:

iptables -F

to flush the firewall tables. Then try to connect.
If you can , then you need to either disable the firewall if it's a test, private network or reconfigure your firewall if it's not.

I can ping the other computer but then i think there's some problem with my config, but i dont know what is it.
Here's the screenshot of my problem.
